SPECIFICATIN forming part of Letters Patent No. 330,864, dated November Z4, 1385.

Application filed June 16, 1885.

To all whom it may con/cern:

Be it known that I, HENRY M. ABBER- oRoMBIE, a citizen of the United States, residing at Kellys Greek, in the county of St. Clair and State of Alabama, have invented a new and useful Improvement in Gultivators, of which the following isa specification, reference being had to the accompanying drawings.

are

My invention relates to an improvement in cultivators; and it consists in the improved construction and combination of devices hereinafter fully described, and particularly pointed ont in the claims.

In the drawings, Figure l is a perspective view of a cultivator embodying my invention. Fig. 2 is a top plan showing the side beams extended. Fig. 3 is a similar view with the side beams drawn in. Fig. iis a detail view.

A B represent the side beams of my cultivator, which are connected together at their front ends by means of diagonal bars G. These bars are bolted at their front ends to the front ends of the beams A B by the bolts D, and are secured at their rear ends to the beams A B by means of yokes E and bolts F. By releasing the nuts from the bolts F the bars C may be moved on the beams A B. A vertical bolt, Gr, extends up through the centers of the bars C, and on this bolt is pivoted a central draft-beam, I-I, to which the team is hitched. This beam is adapted to be moved at any desired angle with respect to the beams A B, so as to throw the draft upon either side of the cultivator, and is secured at any desired point by a bolt or set-screw, I, which passesthrongh the slotted end of au arm, K, that is pivoted on the beam B.

On the upper end of the bolt G is secured a foot, L', to which are fastened the front ends of the bent handles M. These handles are connected near their rear ends to the rear ends of the beams A B by flexible standards N. The rear ends of the beams A and B are connected together by the curved arms O, which are pivoted thereto, and are provided with a series of openings, l?, in their free ends. A bolt, B, is adapted to pass through these openings and secure the curved arms together at any desired point. It will be seen from this construction that the beams A and B may Serial No. 168,893.

be adjusted laterally with relation to each other, and that when so adj usted the outer ends of the connecting-rods C and of the curved arms O are always maintained in their original positions with respect to the side beams.

I am aware that cultivators have been heretofore constructed havingl their side beams connected by cross-bars, which enable them to be adjusted laterally with relation to each other; but when said beams are brought near together, in order to narrow the spaces between the cultivator-teeth, the ends of the cross-bars project beyond the sides of the side beams in the way of the corn or other plants that are being cultivated. This objection I overcome by my construction.

S represents curved standards, which are secured to the under sides ofthe side beams by means of U-shaped bolts T and yokes V. These standards are slotted, as at S, and through these slots extend bolts W, that are employed for clamping the cultivator-teeth to the standards. By loosening the nut-s on the bolts WV the cultivator-teeth may be moved upward or downward on the standards and adjusted at any desired point thereon. If it is desired to change the angle at which the cultivator-teeth enter the ground, it is only necessary to loosen the nuts on the Ushaped bolts and insert the wedges Z between the beams and the standards, as shown in Fig. 3.

Having thus described my invention, I claim- 4 1.
